RBAC API

RBAC API

一个更友好的RBAC API。 这个API是Management API的子集。 RBAC用户可以使用这个API来简化代码。

参考

全局变量 e是实施者实例。

Go

e, err := NewEnforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")

GetRolesForUser()

GetRolesForUser 获取用户具有的角色。

例如：

Go

res := e.GetRolesForUser("alice")

GetUsersForRole()

GetUsersForRole 获取具有角色的用户。

例如：

Go

res := e.GetUsersForRole("data1_admin")

HasRoleForUser()

HasRoleForUser 确定用户是否具有角色。

例如：

Go

res := e.HasRoleForUser("alice", "data1_admin")

AddRoleForUser()

AddRoleForUser 为用户添加角色。 如果用户已经拥有该角色（aka不受影响），则返回false。

例如：

Go

e.AddRoleForUser("alice", "data2_admin")

AddRolesForUser()

AddRolesForUser adds multiple roles for a user. Returns false if the user already has one of these roles (aka not affected).

For example:

Rust

let roles = vec!["data1_admin".to_owned(), "data2_admin".to_owned()];
let all_added = e.add_roles_for_user("alice", roles, None).await?; // No domain

DeleteRoleForUser()

DeleteRoleForUser deletes a role for a user. Returns false if the user does not have the role (aka not affected).

例如：

Go

e.DeleteRoleForUser("alice", "data1_admin")

DeleteRolesForUser()

DeleteRolesForUser deletes all roles for a user. Returns false if the user does not have any roles (aka not affected).

例如：

Go

e.DeleteRolesForUser("alice")

DeleteUser()

DeleteUser deletes a user. Returns false if the user does not exist (aka not affected).

例如：

Go

e.DeleteUser("alice")

DeleteRole()

DeleteRole deletes a role.

例如：

Go

e.DeleteRole("data2_admin")

DeletePermission()

DeletePermission deletes a permission. Returns false if the permission does not exist (aka not affected).

例如：

Go

e.DeletePermission("read")

AddPermissionForUser()

AddPermissionForUser adds a permission for a user or role. Returns false if the user or role already has the permission (aka not affected).

例如：

Go

e.AddPermissionForUser("bob", "read")

AddPermissionsForUser()

AddPermissionsForUser adds multiple permissions for a user or role. Returns false if the user or role already has one of the permissions (aka not affected).

例如：

Rust

let permissions = vec![
    vec!["data1".to_owned(), "read".to_owned()],
    vec!["data2".to_owned(), "write".to_owned()],
];

let all_added = e.add_permissions_for_user("bob", permissions).await?;

DeletePermissionForUser()

DeletePermissionForUser deletes a permission for a user or role. Returns false if the user or role does not have the permission (aka not affected).

例如：

Go

e.DeletePermissionForUser("bob", "read")

DeletePermissionsForUser()

DeletePermissionsForUser deletes permissions for a user or role. Returns false if the user or role does not have any permissions (aka not affected).

例如：

Go

e.DeletePermissionsForUser("bob")

GetPermissionsForUser()

GetPermissionsForUser gets permissions for a user or role.

For example:

Go

e.GetPermissionsForUser("bob")

HasPermissionForUser()

HasPermissionForUser determines whether a user has a permission.

例如：

Go

e.HasPermissionForUser("alice", []string{"read"})

GetImplicitRolesForUser()

GetImplicitRolesForUser gets implicit roles that a user has. Compared to GetRolesForUser(), this function retrieves indirect roles besides direct roles.

For example:
g, alice, role:admin
g, role:admin, role:user

GetRolesForUser(“alice”) can only get: [“role:admin”].
But GetImplicitRolesForUser(“alice”) will get: [“role:admin”, “role:user”].

For example:

Go

e.GetImplicitRolesForUser("alice")

GetImplicitUsersForRole()

GetImplicitUsersForRole gets all users inheriting the role. Compared to GetUsersForRole(), this function retrieves indirect users.

For example:
g, alice, role:admin
g, role:admin, role:user

GetUsersForRole(“role:user”) can only get: [“role:admin”].
But GetImplicitUesrsForRole(“role:user”) will get: [“role:admin”, “alice”].

例如：

Go

users := e.GetImplicitUsersForRole("role:user")

GetImplicitPermissionsForUser()

GetImplicitPermissionsForUser gets implicit permissions for a user or role.
Compared to GetPermissionsForUser(), this function retrieves permissions for inherited roles.

For example:
p, admin, data1, read
p, alice, data2, read
g, alice, admin

GetPermissionsForUser(“alice”) can only get: [[“alice”, “data2”, “read”]].
But GetImplicitPermissionsForUser(“alice”) will get: [[“admin”, “data1”, “read”], [“alice”, “data2”, “read”]].

For example:

Go

e.GetImplicitPermissionsForUser("alice")

GetDomainsForUser()

GetDomainsForUser gets all domains which a user has.

For example: p, admin, domain1, data1, read p, admin, domain2, data2, read p, admin, domain2, data2, write g, alice, admin, domain1 g, alice, admin, domain2

GetDomainsForUser(“alice”) could get [“domain1”, “domain2”]

For example:

Go

result, err := e.GetDomainsForUser("alice")

GetImplicitResourcesForUser()

GetImplicitResourcesForUser returns all policies that should be true for user.

For example:

p, alice, data1, read
p, bob, data2, write
p, data2_admin, data2, read
p, data2_admin, data2, write

g, alice, data2_admin

GetImplicitResourcesForUser(“alice”) will return [[alice data1 read] [alice data2 read] [alice data2 write]]

Go

resources, err := e.GetImplicitResourcesForUser("alice")
